radiation hardened microprocessor space | Military and aerospace electronics

CHANDLER, Arizona – Microchip Technology Inc. in Chandler, Arizona, introduces the SAMRH71 Arm microprocessor and SAMRH707 microcontroller with Arm Cortex-M7 radiation-hardened system-on-chip (SoC) technology for space applications.

Microchip has developed the SAMRH71 and SAMRH707 devices with the support of the European Space Agency (ESA) and the National Center for Space Studies (CNES), the French space agency.

Building on the standard Arm Cortex-M7 architecture and the same peripherals as automotive and industrial processors, the SAMRH71 and SAMRH707 help optimize development costs and schedule using standard software and hardware tools.

The SAMRH71, a radiation hardened variant of Microchip’s COTS automotive SoC technology, offers a combination of spatial connectivity interfaces as well as a high performance architecture with over 200 Dhrystone MIPS (DMIPS).

Designed for high level radiation performance and extreme temperatures, the SAMRH71 Arm Cortex-M7 microprocessor core is coupled to high-bandwidth communication interfaces such as SpaceWire, MIL-STD-1553, CAN FD and Ethernet with IEEE 1588 Generalized Precision Time Protocol (gPTP capabilities).

The device is ESCC qualified with the support of CNES and complies with the high reliability Class V and Q grades of the MIL standard.

The SAMRH707 device provides analog functions on over 100 DMIPS processor units with digital signal processing (DSP) capabilities, combined with spatial connectivity interfaces in a small footprint.

The SAMRH707 integrates static random access memory (SRAM) and flash memory, high bandwidth communication interfaces including SpaceWire, MIL-STD-1553 and CAN FD, as well as analog functions such as an A / N 12 bits and D / A converter.

Developers can use the SAMRH71F20-EK and SAMRH707F18-EK evaluation boards. The devices include the MPLAB Harmony suite of tools, third-party software services for space applications, and the company’s Integrated Development Environment (IDE) for development, debugging, and software libraries. Devices are supported in MPLAB Harmony version 3.0.
